Good grief, this article is a year old. I vaguely remember some hoopla because Bush claimed he had been misquoted.
He was never misquoted. His remark was on TV and just google it, you'll see it. Here's followup from his spokesman later.

Q Scott, the President called the Minutemen in Arizona the same vigilantes that they were before -- I assume he still believes that. And -- but is there any change in his opinion, now that they've actually taken action out on the border this past weekend?
MR. McCLELLAN: I think the question that he was responding to was essentially suggesting that people taking things into their own hands and going after people who are trying to enter the country illegally. We remain concerned about -- well, first of all, if we're talking about people reporting suspicious activity to the proper authorities, that's one thing. And people, if they do see suspicious activity, should notify the proper authorities so that they can take action and go after those individuals. If we're talking about armed, untrained individuals who are seeking to take matters into their own hands, then that is a concern to us. And the reason why it is a concern is because it could lead to people getting hurt. And that's what we want to avoid.
